IMPROVEMENT lN APPARATUS FOR E MPTYING 'P R|VY-VAULTS, SEWER-TRAPS, 55c.

Specification forming part of Letters Patent No. 179,993, dated July 1B, 1876; application n'led June 29, 1875.

To all whom it may concern Be it known that I, JEROME BRADLEY, of Washington, in the District of Columbia, have invented certain new and useful Improvements in Apparatus for Emptying Privy- Vaults, Sewer-Traps, 860. 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being,

and arrangement of the various operative parts, all as more fully hereinafter explained.

In order to enable those skilled in the art to make and use my apparatus, I proceed to describe the same, having reference to the drawings, in which- Figure l represents a side elevation of my improved vacuum. apparatus for emptying privy-vaults Fig. 2, a vertical section through the double-acting pump, as arranged for emptying by vacuum; Fig. 3, sections of the up per portion of the barrel, showing the automatic gage-valve in both its open and closed positions.

. The apparatus consists of a'double-acting air-pump, P, having two ports, a 1), arranged for convenience midway the cylinder and at the upper and lower sides thereof. These ports connectby suitable valved passages 0 cl with the opposite ends of the cylinder, so as to receive and force the air therefrom by the movement of the piston in a manner well understood, and by such operation creating and maintaining a continuous vacuum in the receiving-barrel Q, as each stroke of the piston exhausts and forces the foulairfrom the barrel into the deodorizer.

- The pump is mounted upon a suitable truck, T, for convenience in handling, and the frame is provided with handles H, by which it may,

be carried, putupon andtaken from the wagon, and rolled like a truck or wheelbarrow from place to place. It is operated by a doublehandle socket, h, mounted by suitable bearings upon a strong iron frame, F, secured to the truck-frame; and the piston-rod is united to a hanger or rock arm, G, depending from the axis of the pump-handle, the connection being made by a small roller, 6, carried by the hanger, so as to work in a slot in a yoke,f, on the endof the piston-rod, to allow the latter to be Worked by a rigid arm Without binding the piston-rod. The double handles I are secured in a socket, It, so as to be removable therefrom, and to be applied for use when required.

In the operation of emptying privy-vaults, one end of the. air-suction hose S is attached to the air-inlet port'a, and the other end to the top of a barrel or small tank, and this barrel is put into direct communication with the privy-vault by a hose, J, provided with a suitable coupling for attachment to the top of the barrel, and a pipe for entering the vault. The deodorizer D is a separate attachment, and is connected with the discharge-port b by a hose, E, having suitable couplings, and

through which foul air taken into the barrel in the process of tilling it is exhausted there from through the pump and forced into the,

deodorizer, which consists of a metallic charcoal-burner or a receptacle for chemicals, into which the foul air isi'orced directly from the airpump as fast as it is exhausted from the barrel being filled with matter. By these -separately-connected parts the barrel and the pump may be placed in the most convenient position, and the deodorizer situated at or very near the open vault, and thus serve to deodorize the offensive odor arising therefrom, while also'disiu fecting the air sucked from the barrel.

The hose must be of sufficient length to allow of placing the parts where desired. The deodorizer must, of course, be properly prepared before it is put in connection with the pump, and the couplings otithe hose must be such as to allow of ready attachment and separation. The convenience of utilizing the deodorizer to render the foul air from the open vault inoffensive is a very important matter; but when such deodorizer serves at the same time to destroy all the foul air exhausted from the barrel, its utility is thereby increased.

The hose .T, through which the matter is drawn into the barrel Q, need be comparatively short, and it is provided with a suitable metallic mouth piece, attached by a swivelcoupling or 0th rwise.

The barrels are provided with proper couplings for the hose, and when'lilled can be transported to any suitable place and emptied for use again, being provided for that purpose with suitable sealed openings in one end.

The hose for conducting the matter and discharging the air being properly connected, and the pipe end being adjusted in the vault, the

operation of the double-acting pump at once pump there is no necessity for the use of a vacuum storing-chamber, as a few strokes of the pump. will create a sufficient vacuum to cause the matter to pass quickly and continuously through the immersed end of the liftinghose J until the vault is emptied. In this way the barrel may be filled at once, or carried from place to place and filled from the contents of several vaults. To ascertain when it is filled, I have combined with the exhausthose and the barrel a gage-valve, g, showing in the drawing as a puppet-valve; but it may be of any construction and arrangement that will answer the purpose. It is placed in the exhaust-coupling, and is made as light as possible, either of wood or cork, to float upon the surface of the matter as it rises in the barrel, and automatically close the opening inthe exhaust-pipe coupling Z. The weight of the valve keeps it open and hanging by its stem i, which depends from a gnidein the coupling Z, and extends down into the barrel a short distance, so that, as the matter approaches thetop of the barrel, it lifts the valve and closes the air exhaust passage, the effect of which is to immediately stop the pump, and prevent the further working of the apparatus.

Having thus described my invention, what I claim as new therein, and for which I desire Letters Patent, is'

1. In combination, in a machine for cleanin g privy-vaults, an air-pump, a suitable flexible pipe, connecting said air-pump with the top of a barrel intermediate between said pump and the vault to be cleaned, a floatvalve in the aifiexhaust pipe, and a suitable flexible pipe to lead from said barrel into said vault, the pumpand barrel being independently movable relatively to each other and to the vault, substantially as and for the purposes set forth. y

2. In combination, in a machine for cleaning privy-vaults, a barrel for receiving fecal matter, with its lower end always closed, and having an opening in its top, through which, by exhaustion of air in the barrel, fecal matter is forced to flow into said barrel, and a float-valve arranged in the air-exhaust pipe,

substantially as and for. the purposes set forth.

In testimony that I claim the foregoing I have affixed my signature in presence of two witnesses.

JEROME BRADLEY.
